Filter by:Endoscopic sinus surgery (ESS) is a common otolaryngologic procedure that aims to remove the partitions that separate the sinus cavities, remove inflamed tissue, and optimize the sinuses for topical medication use. In this procedure, the surgeon will inject a combination of drugs, local anesthetics, and vasoconstrictors, to reduce bleeding and improve visualization. However, previous studies have shown similar results when injected with only saline. In this study, investigators want to determine if the injection of local anesthesic+vasoconstrictor compared to no injection at all makes any difference in improving the surgeon's visualization during an ESS.
To evaluate the effect of using a mathematical model developed through pre- and post-surgical hemoglobins to predict the volume to aspirate in patients undergoing primary body liposuction.
A three-arm randomized controlled non-inferiority pilot study comparing anticoagulation strategies using unfractionated heparin, argatroban and enoxaparin for extracorporeal membrane oxygenation support conducted as an investigator-initiated, prospective, parallel group, open-label, active comparator controlled, single center, phase IV study to evaluate the non-inferiority of enoxaparin or argatroban for anticoagulation during ECMO therapy in comparison to the current standard, unfractionated heparin, as measured by the incidence of thromboembolic events during the duration of ECMO therapy
Patients with colorectal cancer (CRC) have a higher risk of both venous thromboembolism (VTE) and major bleeding (MB). Patients with CRC are underrepresented in the major trials examining treatment of cancer-associated VTE with anticoagulant.
To compare the outcomes of plastibell circumcision method with open surgical technique in infants presenting at tertiary care hospital. Methods This randomized controlled trial (NCT??) was conducted at Pediatric surgery department, the Children's hospital and the University of Child health, Lahore. Study was carried out over a period of six months from 11-01-2022 to 11-07-2022. Non probability, purposive sampling was used. 174 infants presenting for circumcision were admitted and assigned a method of circumcision randomly. They were randomly divided in to 2 groups by using opaque sealed envelope technique. Infants in group A were underwent plastibell circumcision while infants in group B were underwent open technique circumcision. 87 circumcisions were performed by each method. The informed consent was taken from parents for inclusion into the study. All infants were underwent circumcision under local anesthesia as per assigned method. Same preoperative, per-operative, and postoperative care was given to each regardless of the technique. These patients were followed for 3 hours to assess bleeding as per operational definition. Then followed on an outpatient basis every 6th day until complete healing is achieved (30 days).The data regarding age, weight, duration of procedure, wound infection and post circumcision bleeding was recorded in a predesigned performa. (As per operational definition).
The BRACKETS pilot study is a multicentre, prospective, randomized controlled trial of prophylactic preoperative tranexamic acid (TXA) versus placebo and, using a partial factorial design, of prophylactic preoperative desmopressin versus placebo.
The investigators will test the hypothesis that utilization of a blood and blood component transfusion algorithm guided by the POC Quantra QPlus System in patients undergoing complex cardiac surgery will reduce RBC, plasma, cryoprecipitate, and platelet transfusion during surgery and the first 12 postoperative hours, compared to standard of care (central laboratory transfusion monitoring at the primary anesthesia provider's discretion).
The aim of this clinical study conducted in accordance with the information in the literature is to compare the effects of administering tranexamic acid during orthognathic surgery, at different doses. Specifically, investigators aim to compare the effects of administering 1 ampoule IV (approximately 3 mg/kg) and 2 ampoules IV (approximately 6 mg/kg), and evaluate their impact on intraoperative bleeding (ml), surgical duration (min), postoperative swelling, and intraoperative surgical field evaluation (Fromme Scale), by comparing them with control group (applying no drug administration) patient data.
Nowadays robot-assisted radical prostatectomy (RARP) has become the standard surgical treatment for localised prostate cancer. The robotic approach has been proven superior to open retropubic prostatectomy (ORP) in terms of surgical-related morbidity: RARP has in fact been associated with significantly lower estimated blood loos (EBL), lower transfusion rate, less length of stay, shorter catheterization time, lower risk of Clavien-Dindo grade II and III complications, lower risk of vesicourethral anastomotic stricture and less post-operative pain. The optimal anatomical visualisation and the extraordinary maneuverability, along with the tamponade effect of the pneumoperitoneum, are surely to be deemed responsible of this statistically significant differences. However, to this day no study has ever investigated the prognostic significance of haematological parameters in terms of predicting perioperative bleeding risk in patients undergoing RARP. Therefore, the investigators conducted a retrospective non-interventional cohort study to gather evidence concerning the impact of anemia and thrombocytopenia on bleeding risk following this surgical procedure. Furthermore, the investigators evaluated associations between demographical, pathological and surgical factors and hemorrhagic complications. The investigators retrospectively evaluated all the patients that underwent robot-assisted radical prostatectomy in our Urology Unit from the 1st of January 2017 to the 31th of December 2020. The investigators collected demographic, clinical and pathological data from the medical records of these patients, with particular attention to other known risk-factors for RARP-associated bleeding (e.g.: volume of the prostate, body mass index, smoking status, nerve sparing technique). Complications were analyzed according to the Clavien- Dindo classification. Bleeding was assessed by considering both the hemoglobin (Hb) drop after surgery and the fluid intraoperatively collected in the suction canister, with all the due adjustments. Moreover, post-operative haemorrhagic complications were evaluated. The investigators included patients not younger than 18 years old, of which records of a pre-operative full blood count in the 30 days prior to the surgery along with a full blood count the day after were available. Criteria for exclusion were a history of congenital coagulopathies and/or congenital thrombocytopenia and patients that underwent salvage radical prostatectomy after radiation therapy. Statistics: EBL and operative time learning curve is studied. Clinical, pathological, intraoperative risk factors analysis for higher EBL is performed by linear regression modelling. Factors are evaluated independently and jointly. Association between each factor above and post-operative outcomes (i.e. post-op bleeding, need of transfusion and hematuria) is also assessed.
The purpose of the study is to explore the safety and efficacy of UCMSC-Exo in consolidation chemotherapy-induced myelosuppression in patients with acute myeloid leukemia after achieving complete remission.
